Questione giuridica chiave
Whether the public-law appeal was admissible despite the general bar on immigration-bewilligung disputes.
Decisione estratta
It was admissible only insofar as the appellant could rely on Article 8 ECHR through his relationship with his minor daughter; otherwise no enforceable right existed.
Motivazione estratta
No federal-law right to the permit existed; the former marriage to a Swiss citizen could no longer be relied upon because no right to settlement had been acquired. A potentially protected family-life claim remained only as to the minor daughter with settled residence.
